Abstract :
We demonstrate strong-field photoemission from plasmonic nanoparticles by ultrashort pulses. Significant (x110) field enhancement attributed to surface plasmons enable 25-eV electron generation in nano-localized fields around nanoparticles. Correlation between plasmonic resonance and electron spectra is shown.
